Subject: [PATCH v2 4/8] wl12xx: report invalid TX rate when returning non-TX-ed skbs
Date: Wed, 23 Feb 2011 00:22:27 +0200	[thread overview]
Message-ID: <1298413351-15462-5-git-send-email-arik@wizery.com> (raw)
In-Reply-To: <1298413351-15462-1-git-send-email-arik@wizery.com>

Report a TX rate idx of -1 and count 0 when returning untransmitted
skbs to mac80211 using ieee80211_tx_status(). Otherwise mac80211
tries to use the returned (essentially garbage) status.
